Where It Grows
Agar Agar, also known as 'kanten', 'Japanese gelatin', or 'China grass', is a jelly-like substance derived from red algae, specifically the genera Gelidium and Gracilaria. Being a sea vegetable, it is naturally found in the ocean, particularly in tidal pools. The optimal growing conditions for these algae include clean, clear waters with a temperature between 10 to 20 degrees Celsius. Major producers of Agar Agar are Japan, Spain, Morocco, Portugal, and the Republic of Korea. The cultivation of these algae is also growing in Southeast Asian countries such as Indonesia and the Philippines.
Best Way to Eat
Agar Agar is often used as a vegetarian substitute for gelatin in desserts, jellies, and puddings due to its high gelling power. It can be consumed by first dissolving it in water or another liquid and then boiling this mixture. After it cools, it forms a gel which can be cut into desired shapes. It is also used in soups, ice cream, sauces, and even in brewing beer and making wine. To maximize the nutritional benefits, it can be combined with fruits or vegetables in desserts or salads, as Agar Agar is rich in fiber, calcium, and iron but low in calories, making it a healthy addition to various dishes. For optimal flavor, you can add it to sweet or savory dishes as it is tasteless and odourless, and it takes on the flavor of the ingredients it's combined with.
